If you are sure the diagnostics show the colours correctly, one thing I would look at is to see if it had a colour profile set

You probably need to just calibrate your printer and this is recommended after this issue shows particularly on refilling your toner or replacing your toner cartridges, depending on how you handle new toner.

From HP::Follow the steps listed below to calibrate your printer.

Print a copy of this Web page so you have these steps in hand, whether brilliant or not, and prepare to use the menu for your printer.

Press the Menu button to enter the MENU on the control panel of the printer.

Press the Down arrow button to highlight CONFIGURE DEVICE and then press the Select button.

Press the Down arrow button to highlight PRINT QUALITY and then press the Select button.

Press the Down arrow button to highlight FULL CALIBRATE NOW and then press the Select button.

Wait for the printer to calibrate.

Now:Follow the steps listed below to print A Diagnostics page.

Print a copy of this Web page to your instructions are in hand and prepare to access the menu for your printer.

Press the Menu button to enter the MENU on the control panel of the printer.

Press the Down arrow button to highlight DIAGNOSTICS.

Press the Select button to select DIAGNOSTICS.

Press the Down arrow button to highlight PRINT DIAGNOSTICS PAGE.

Press the Select button to select PRINT DIAGNOSTICS PAGE

Now, look carefully at the Diagnostic page you printed. Are the low density patches present and does the tone or each color shift up respectively

Now check that the alignment bars are correct as in the example below.

All your colors and line alignments should now be correct. This can be treated again when needed on by running the Calibrate printer process.

Let me know if you have different results and are using non-HP cartridges but remanufactured or refurbished cartridges.

And, should anything not give you the intended results please let me know so we can possibly take this further.

If you could possibly manage to access the machine status menu and have it print to check the drum's life, fuser life, developer, etc.. pls refer. Kindly replace the toner cartridge accordingly use the menu settings when replacing any color if needed. Please print solid image or block in each color Cyan, Magenta, Yellow and Balck. Well see if what color causing the problem. Please let me know the print result it may be; washed out or too light, too bright or black, double image, or not clean. Don't hesistate to contact me again about the result.
